| Parameter | Value |
|---|---|
| Diode type | Standard |
| Mounting | Through Hole |
| Voltage - DC reverse (Vr) | 500 V |
| Voltage - forward (Vf) (Max) @ if | 2 V @ 5 A |
| Current - reverse leakage @ vr | 40 µA @ 500 V |
| Current - average rectified | 5A |
| Operating temperature - junction | 150°C (Max) |
| Speed | Fast Recovery =< 500ns, > 200mA (Io) |
| Package | Bulk |
| Case | TO-220-2 |
| Reverse recovery time | 16 ns |
16 ns reverse recovery time at 5 A forward current. 2 V forward drop at 5 A is the conduction-loss side of the trade-off.
The tab is electrically common with the cathode — account for isolation when bolting to a grounded heatsink. 40 µA reverse leakage at 500 V is the high-temperature design point; derate the junction temperature below the 150 °C maximum for long-life PFC stages.
Active lifecycle status — no last-time-buy or phase-out notice on this part.
The evidence does not list a BYC5D-600 variant or any cross-reference. The 500 V rating on this part is the only voltage class confirmed; verify the 600 V requirement against your circuit's peak repetitive voltage before substituting.
